| Abstract: | The reaction of dichlorides of 3,3-disubstituted allenylphosphonic acids with chlorosulphonylisocyanate involves (2+2)-cycloaddition of the reagent at the C2-C3 double bond and results in the formation of 1-chlorosulphonyl-3-dichlorophosphonylmethyliden-2-azetidinones, until now inknown in the literature. |
